ENERGY STAR® is a government-endorsed certification that identifies products from various industries that meet stringent energy performance standards. The ENERGY STAR® symbol is proof a product has been independently tested and verified to deliver superior energy efficiency. In any given industry, only the top 15% to 30% of products meet the rigorous energy efficiency standards held by ENERGY STAR®.
In the window industry specifically, a company must have its windows tested by an accredited third party to be considered for ENERGY STAR® certification. Our windows and doors have surpassed industry standards through extensive heat-loss and/or air leakage testing, in conjunction with an analysis of their potential solar gain.
Certified windows are 20% more energy efficient than the average window.
Certified doors are 15% more energy efficient than the average door.
Energy Savings
ENERGY STAR®-certified windows and doors are designed to minimize heat transfer, which helps to reduce the workload on your heating and cooling systems. This lowers your energy consumption and decreases utility bills.
Increased Comfort
Windows and doors with the ENERGY STAR® symbol are proven to help maintain consistent indoor temperatures, creating a more comfortable living space for you and your family throughout the year.
Improved Indoor Air Quality
ENERGY STAR®-certified windows and doors create a stable indoor environment. This reduces the need for excessive ventilation, which in turn prevents outdoor pollutants from entering your home.
Reduced Environmental Impact
Energy-efficient windows also reduce greenhouse gas emissions. Choose ENERGY STAR® products to play your part in protecting the environment while enjoying lower energy costs.
Energy-efficient windows play a crucial role in reducing energy consumption and enhancing overall building performance. By utilizing advanced technologies such as low-E coatings, multiple panes, and gas fills, energy-efficient windows minimize heat transfer and improve insulation.
This results in reduced reliance on heating and cooling systems, lower energy bills, enhanced comfort, and a smaller carbon footprint. Energy-efficient windows also contribute to a more sustainable future by reducing greenhouse gas emissions and conserving natural resources.
Investing in energy-efficient windows is a cost-effective way to improve energy efficiency, save money, and promote environmental stewardship.

The first thing to consider is your budget and design preferences. Understanding these basic factors will help guide your choices.
Next, look into the specifics of the product you’re buying. Consider its U-factor and how much solar heat can enter through the window by determining its Solar Heat Gain Coefficient (SHGC). Evaluate the glazing options offered by your manufacturer. Also, be sure to choose a frame with good insulation properties to minimize air leakage or condensation.
Finally, consult with professional installers so they can give you personalized recommendations on how to make your home more energy-efficient.

To qualify for ENERGY STAR® certification, a product must meet specific energy performance criteria established by the U.S. Environmental Protection Agency (EPA). The criteria vary depending on the product category, such as windows, doors, appliances, or electronics. Manufacturers are responsible for testing their products in EPA-approved laboratories or by certified third-party testing organizations.
Any product that is ENERGY STAR® certified will be listed on the Natural Resources Canada website in the ENERGY STAR® section. You can also spot the label on our windows and doors!
To reduce the risk of buying tampered products, customers should only buy ENERGY STAR® certified products that are certified by reputable, accredited third parties that conduct regular audits and test products in-house with several different methods.
Yes. It updates its criteria every five to seven years.
The U-factor is the rate at which a window loses heat—the lower the number, the slower the heat loss. Meanwhile, ER is a formula that considers the U-factor (heat loss), air leakage, and the benefit of potential solar gains of a window—the higher the value, the higher the potential for energy savings.
Low-E glass means a special coating was applied to the glass to improve energy efficiency. Windows installed in Canada should have a low U-factor coupled with a very high solar heat gain coefficient. Together, you get year-round energy savings!
